Hamwe nogukomeza kwiyongera kwingufu zikenewe, biteganijwe ko isoko yubushobozi bwa firime mubushinwa izongera kwinjira mugihe cyiterambere ryinshi mumyaka mike iri imbere.Filime ya polypropilene, ibikoresho byibanze bya capacitori ya firime, ikomeje kwagura itangwa ryayo nibisabwa bitewe no kwaguka byihuse kubisabwa no kurekura buhoro buhoro umusaruro.Icyumweru cyo muri iki cyumweru kizareba ibintu by'ibanze bya capacitor- firime ya polypropilene (film ya PP).

Mu mpera z'imyaka ya za 1960, firime y'amashanyarazi ya polypropilene yabaye imwe muri firime eshatu zikomeye z'amashanyarazi kubera imiterere yihariye y'amashanyarazi no kuyitunganya ndetse no gukora neza cyane, kandi yakoreshejwe cyane mu nganda zikoresha amashanyarazi.Mu ntangiriro ya za 1980, umusaruro wa capacitori ya firime ya polypropilene wari umaze gutangira mu bihugu byateye imbere mu Burayi no muri Amerika, mu gihe Ubushinwa bwari bukiri mu cyiciro cy’iterambere ry’imashanyarazi ya polipropilene.Gusa binyuze mu kumenyekanisha ibyuma bya polypropilene ya firime ya capacitor ikora ibikoresho nibikoresho byingenzi twabonye ibyuma bya firime ya polypropilene muburyo nyabwo.

Reka tumenyane no gukoresha firime ya polypropilene mubushobozi bwa firime hamwe nintangiriro ngufi.Ububiko bwa firime ya polypropilene ni mubyiciro bya capacitori ya firime, uburyo bwayo ni firime ya polypropilene, electrode ifite ubwoko bwicyuma nubwoko bwa firime yicyuma, intandaro ya capacitori ipfunyikishijwe na epoxy resin cyangwa igizwe na plastike nicyuma.Umuyoboro wa polypropilene wakozwe na electrode yicyuma cyitwa metallized polypropylene film capacitor, ikunze kwitwa capacitor.Filime ya polypropilene ni resimoplastique ikozwe na polymerizing propylene.Ubusanzwe ni mubyimbye, bikaze, kandi bifite imbaraga zingana, kandi birashobora gukoreshwa muma firime ya parike, imifuka itwara imizigo, nibindi. 0. 90-0.91g / cm³.Nimwe mubwoko bworoshye bwa plastiki zose ziraboneka.Irahagaze neza cyane kumazi, igipimo cyo kwinjiza amazi mumazi ni 0. 01% gusa, uburemere bwa molekile hafi 80.000-150.000.

Filime ya polypropilene nibikoresho byingenzi bya capacitori.Uburyo bwo gukora bwa capacitori ya firime yitwa metallized film, ikorwa na vacuum ihumeka icyuma cyoroshye kuri firime ya plastike nka electrode.Ibi birashobora kugabanya ingano yubushobozi bwa capacitori yububasha, firime rero iroroshye gukora capacator ntoya.Hejuru ya capacitor ya firime ikubiyemo cyane cyane firime shingiro, icyuma gifata ibyuma, insinga, gupakira hanze, nibindi. Muri byo, firime shingiro nibikoresho fatizo fatizo, kandi itandukaniro ryibikoresho bizatuma ubushobozi bwa firime bugaragaza imikorere itandukanye.Filime shingiro muri rusange igabanijwemo polypropilene na polyester.Umubyimba mwinshi wa firime shingiro, niko hejuru ya voltage ishobora kwihanganira, naho ubundi, niko voltage ishobora kwihanganira.Filime shingiro ni firime ya elegitoroniki ya elegitoroniki, kuko dielectric ya capacitori ya firime nicyo kintu cyingenzi cyane cyo hejuru cyo hejuru, kigena imikorere ya capacitori kandi kigatwara 60% -70% yikiguzi cyibikoresho.Ukurikije uko isoko ryifashe, abahinguzi b'Abayapani bafite icyerekezo cyiza mubikoresho fatizo bya capacitori zo mu rwego rwo hejuru, hamwe na Toray, Mitsubishi na DuPont aribo batanga amasoko meza ya firime ku isi.

Amashanyarazi ya polypropilene kumashanyarazi mashya, ingufu za Photovoltaque nuyumuyaga byibanda cyane kuri microne 2 na 4, kandi ubushobozi bwo gukora bwagabanutseho igice kirenga kimwe cya kabiri mugihe kimwe ugereranije na microne 6 kugeza 8 kubikoresho bisanzwe byo murugo, bikavamo mu kugabanuka gukabije k'umusaruro wose hamwe no guhindura isoko n'ibisabwa.Gutanga amashanyarazi ya polypropilene bizagabanuka mumyaka iri imbere.Kugeza ubu, ibikoresho by'ingenzi bya firime y’amashanyarazi ya polipropilene ikorerwa mu Budage, mu Buyapani no mu bindi bihugu, kandi ubwubatsi bw’ubushobozi bushya ni amezi 24 kugeza 40.Byongeye kandi, ibisabwa mu mikorere ya firime nshya y’ingufu zikoresha ingufu ni nyinshi, kandi ibigo bike ni byo byonyine bishobora guhagarika umusaruro mwinshi w’amashanyarazi mashya y’amashanyarazi ya polypropilene, ku isi yose rero, nta bushobozi bushya bwo gukora firime ya polypropilene mu 2022. Ubundi ishoramari muri imirongo yumusaruro iri mu biganiro.Kubwibyo, hashobora kubaho icyuho kinini cyubushobozi bwinganda zose umwaka utaha.
